*TL;DR:*

SCX files are a bit more difficult, but not by much. The approach is the

same.

SCX and VCX are opened in the system data session when you execute them.

Code injection allows you to copy those files out of the running

application.

Code in the OBJCODE is never encrypted. Clearly visible when you look at

the help file for the COMPILE command and the ENCRYPT option.

The report designer is always the easiest. If you let the user modify

reports try this in your EXE: Open the report designer, right click to open

the data environment, right click to add a file. Pick Other. In the file

open dialog enter the name of a VCX or SCX file that is embedded in the

EXE. The name must be in quotes. You will see the file being available in

the report data environment.
